Specification of Letters Patent.

Patented July 25. 1905.

Application filed February 6, 1905. Serial No. 244 418.

lie it known that l, SAMUEL Orson, a citizen of the United States, residing atUhicago, in l)l3L.C(;Lliii oi Cook and State of lllinois, have invented certain llGV and useful improvements in Pneumatic i1rain-lClcvatoi-s; and l do ilcciarc the following to be a full, clear, and t (lcscription oi the invention, such as will enahio otlacrs skilled in the art to which it appertains to in: he and use the same.

This imrniion rclatcs to improvemcnts'in pneumatic llll-QlOYZltOlS.

The obja t oi thc invention is to provide an vator of this character whereby grain may removed or unloaded from cars, boats, or .er places and elevated into asuitable tank or receptacle from which it may be deposited into a weighing-hopper or other desired reand freed from all dirt and dust while being deposited into said tank or receptacle.

lv'ith the above and other objects in view the inventionconsistsof certain novel features oi construction, combination, and arrangementof parts, as will be hereinafter described and claimed.

' In the accompanying drawings, Figure 1 is a side elevation of the invention. Fig. 2 is a vertical sectional view of the same; and Fig. 3 is a horizontal sectional view through the grain receptacle or tank, taken above the pm,

, and of the tank 1 and through the partitions is the end of a grain-suction pipe 6, to the lower end of which may be connected afiexible suction-hose '7, adapted to be run into a car oiinto the hull of a \cssel and through which and the pipe 6 is adapted to be drawn the grain contained in said car or boat. Above the sides of the same above said partition.'

The opposite end of the pipe 8 is connected with a fan-casing 9, in which is arranged a fan 10, on the shaft of which is mounted a drive-pulley 12, with which is adapted to be connected any suitable driving mechanism. (Not shown.)

When the fan 10 is operated, a strong suc' tion will be created through the pipe 8, thus exhausting the air from the tank 1 and the suction-pipes 6 and 7, which will draw the grain up through said suction'pipesand cause the same to be deposited in the tank 1. As the grain falls from the end of the pipe 6 the dust, dirt, and foreign matter will be separated there-1 from by suction in said tank and will be carried through the openings 5 into and through thepipe 8 to the fan-casing and from thence will be driven into suitable cyclone dust-collectors. (Not shown.)

A grain -elcvator constructed as herein shown and described will be simple, strong, and durable in construction, eflicient in use, and well adapted to the purpose for which it is designed.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and the'minor details of construction may be resorted to without departing frornthe principle 0r sacrificing any of the advantages of this invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

In a pneumatic grain-elevator, the combination of a suitable tank or'reccptacle having arranged therein near its upperend a horizontally-disposed partition, having apertures therein, agrain-suction pipe passing through the topot' said tank and connected to said partition in line with an opening therein, an air suction pipe connected to the top of the tank and communicating with said tank above said 7 meme pzirtition, an exhanst-fanehamber connected In testimony whereofl havehe enntese Wlth the opposlte end of sand an-suction plpe, hand in presence of two subscribing NH-L13" an exhaust-fan arranged in said chamber, a v W T Wr A. F "11) fleznble suct10n-tube secured to the lower end SM of smd gram-dilation pipe and a dlscharge- W1tnesses:

valve arranged In the lower end of said tank, L. T. RE'IGSTAD,

substantially as described. BERENT F. NELSON.
